Feat/user role management

[gallayl]

🎭 Summary

• Added user role management UI accessible from App Settings → Identity → Users
• Expanded role system to support 4 roles: admin, media-manager, viewer, iot-manager
• Each role has metadata (display name, description) for UI presentation
• Users can be listed, viewed, and have roles edited by admins
• Includes validation to ensure users always have at least one role

✨ Features

• User List Page: Displays all users with their roles, creation date, and edit actions
• User Details Page: View user info and manage roles with add/remove/restore functionality
• RoleTag Component: Visual tag for roles with variant styles (default, added, removed)
• UsersService: Frontend service with caching for user queries

🔧 Infrastructure Changes

• Improved Playwright config with better timeouts and CI serialization
• Updated testing guidelines with user journey patterns and parallel test isolation
• Added e2e/tsconfig.json for E2E test TypeScript configuration
• ESLint config updated to use projectService instead of project

🧪 Test Plan

• Unit tests for UsersService (cache behavior, API calls, error handling)
• Unit tests for UserListPage (rendering, navigation, retry)
• Unit tests for UserDetailsPage (role editing, validation, save/cancel)
• Unit tests for RoleTag component (variants, interactions)
• Unit tests for role definitions
• E2E test covering complete user management workflow
• Verified existing E2E tests still pass
